Okay, so, I'm planning on making a pretty standard Tower Defense game, nothing too special, it's going to be track-based, as in, critters go from point A to B on a fixed path, sort of, and you have to build towers around it and stuff. Going to make a design document for it first though, so nothing too special.

But here's my thoughts. I want to give it multiple themes, as in, there are different themed towers you can build, all doing different things. Now this will be tough to ballance, not to mention tough to make each tower different from one another, but it's doable. The thing is, I first need to establish the themes I'm going to use. I do know I'm going to make it a pretty cheerful game, nothing too serious. Potential themes are Fantasy, Western, Horror, Sci-Fi, Medieval and Urban. Perhaps Farm, Music and Army also.
